Data Center Generators Market Worth $9.79 Billion by 2031

According to MarketsandMarkets™, the global data center generators market is projected to grow from USD 8.57 billion in 2026 to USD 9.79 billion by 2031, representing a CAGR of 2.7% during the forecast period.

Modular facilities require scalable and easily deployable backup power solutions that can be integrated quickly with minimal on-site installation complexity. This trend is encouraging the adoption of containerized and plug-and-play generator systems that offer flexibility, rapid commissioning, and simplified maintenance.

Generators Above 3 MW Expected to Grow Fastest

By power rating, generators above 3 MW are expected to record the highest CAGR.

The above 3 MW segment is projected to register the fastest growth in the data center generators market as operators increasingly build hyperscale and AI-oriented facilities with extremely high power requirements. Large cloud providers and colocation companies are deploying multi-building campuses equipped with high-density servers, GPU clusters, and AI training infrastructure, all of which require large-scale backup and continuous power capacity.

Growing investments in mega data center projects across North America, Europe, the Middle East, and Asia Pacific are further accelerating the adoption of generators above 3 MW. In addition, increasing pressure to ensure uninterrupted uptime during grid instability and rising electricity demand is encouraging operators to deploy robust, high-capacity power systems capable of supporting long-duration operations and parallel generator configurations for improved resilience and reliability.

Diesel Generators Expected to Hold Largest Market Share

By type, diesel generators are expected to hold the largest market share.

Diesel generators are expected to retain the largest share of the data center generators market due to their proven reliability, fast-start capability, and ability to deliver uninterrupted backup power during grid failures.

These generators offer high power density, strong load acceptance, and operational stability for mission-critical environments, particularly in large-scale deployments above 3 MW. In addition, diesel fuel infrastructure is widely available across developed and emerging markets, supporting easier deployment and maintenance.

Continuous advances in fuel efficiency, emissions-reduction technologies, digital monitoring, and compatibility with renewable fuels such as hydrotreated vegetable oil (HVO) are also helping diesel generators remain competitive despite growing interest in gas and hybrid alternatives.

North America Expected to Remain Largest Market

North America is projected to account for the largest market during the forecast period.

The region hosts some of the world’s largest data center hubs, including Northern Virginia, Texas, California, Arizona, and Toronto. Continuous investments in AI, cloud computing, and edge infrastructure are driving demand for reliable backup power systems.

The increasing deployment of high-density AI servers and large hyperscale campuses is accelerating the adoption of high-capacity generators, particularly those above 3 MW.
